To all whom it may concern:

Be it known that I, WILLIAM F. OLIN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Platform Adjustments for Harvesters, of which the following is afull description, reference being had to the accom panying drawings, in which- Figure l is a stubble side elevation of the devices for adjusting the platform and main frame on the main supporting-wheel; Fig. 2, a plan view of the same parts; Fig. 3, a perspective view of arrangements' of elastic links for counterpoising the weight of the main frame as far as it is supported on the main wheel. Fig. 4 is a grain-side elevation. Fig. 5 is a plan view ofthe platform-frame shortened by cutting away parts of the sills. Fig. 6 is a perspective view of the divider-post. Fig. 7

f is a perspective of the divider frame or truss divested of all other mechanism. Fig. 8 is a perspective of the pivot-block for the grainwheel arm,showing certain projections thereon by which it is operated and guided.

'Ihe object of my invention is to improve the construction of the divider and platform and to render the adjustment of the platform ou its supportingwheels easy to the operator.

In general form my present machine does not differ materially in form from that shown in Patent No. 326,884, September 22, 1885,

granted to me.

In the drawings, A is the main supportingwheel, its axle journaled in the bearings a, formed in the swinging yokes or arms a2, pivoted at a and a3 to the main supporting-bars E and E2 of the frame. Projecting upward at nearly a right angle to the arms a2 are the arms b and b. These arms serve as levers, by the movement of which the platform is raised or lowered on the master-wheel.

C is a shaft crossing the frame forward of the wheel A and journaled in bearings, and adapted to be given a half-revolution in either direction by means of the worm and wormwheel c'2 and c3. Projecting from this shaft are the arms c and c', and connecting these arms with those b and b are the links D and D. The worm-shaft is provided with a crank, by which it may be turned, and by the operation of the parts already described the frame is adjusted in height relative to the grain to be cut--that is to say, when the worm-shaft is revolved so as to rock the shaft C, to cause its crank-arms c and c to move up and forward, the links D and D draw the upper ends of the lever-arms b and b forward and swing the lever-arm a2 upward, and therebylift the frame, of which the bars E/ and E2, pivoted to said lever-arm a2, form a part, and the reverse revo- 6o luton of the screwshaft will lower said frame.

To reduce the amount of power required to raise the frame, I provide the elastic links F and F, hooking into eyes in projections on the cross-bar E of the main frame, their rear ends connected pivotally to the links D D', which are elongated rearwardly to permit the use of elastic links of sufficient scope. These links may be constructed in any well -known manner; but I prefer the form shown, wherein a tube 7o (preferably a skeleton) incloses a spiral spring abutting against one end of the tube, and having at its other end a nut, f, adapted to slide in the tube, and a rod, f, sliding through the end and threaded into the nutfs. By unhooking the ends of the rods fand turning them they may be screwed into the nutsf3 and the tension of the springs increased or decreased at will. For any further adjustnient of the tension of the springs the shaft 8o di may be placed in any of the holes d5 in the bars D and D. I also can use the holes d5 for adjusting the arms b and b in a different position.

The divider is constructed of angleiron mainly, in the form of a truss having the horizontal part G, forming the lower truss-bar or chord of the truss, fitted to the grain end of the platform-sills I I', and having the sloping portions G and G2, together forming the up- 9o per truss-bar or arch of the truss. I prefer to make the last two parts as one piece, as shown, and also to have them and the portion G bent from a single bar. At their front ends the bars may be welded or riveted. To complete the truss, I place at thc widest spread of the angle-bars the post H, bolted thereto and to the sill I, and form the strut for the truss. In order to prevent lateral movement of the point of the divider, I kprovide the brace G5, roo

trolled by the lock-lever mi.

which extends from the point of the divider rearward and grainward, and at the rear end is secured to the grain end of the finger-bar, vwhich for that purpose is extended grainwardbeyond its securement to the divider-truss. The vpost H is slottednearly its whole length and curved, as shown in Fig. 6.l

K is a supplemental frame, pivoted to the pin K at its rear end, and formed of anglebars V7c and la', bolted at front to the pivot-block 7a2. Said pivot-block has two forwardly-proj ecting lugs, kl, inthe same vertical plane, and between them the forwardly-projecting hook las, considerably. longer than the said lugs. The hook las protrudes through the slot h in the post H, and has hooked onto it a chain, M',which passes downward and in part around the sheave ki", which is fastened on post H, thence horizontally along over the finger-bar toward the stubble end and around the sheave m2, thence forward to the quadrant ma, con- By the movement of this lever the chain is drawn or relaxed at will, and rthus the grain endy of the platform raised or lowered. The lugs k7 constitute journal-bearings for the anti-friction rollers k3, which travel up and down between the flanges hm h1", which are formed on the reat` face of the lpost H, parallel with the slot h', and said rollers, by virtue ofthe distance by which they are vertically separated, serve to keep the supplemental frame K and the pivot block k2 in their proper vertical position,while free to swing up and down. Obviously, the rollers [c5 might travel in the slot h' if it were convenientto make it wide enough, and the iianges hm h1 may be considered as forming a wider continuation of the slot.

To the pivot-block k2, I joint th'e wheel-arm L, and to this 'arm secure my grain-wheel adf justably, so that its position may be changed to increase the scope of adjustment of the platform. lIhe yoke or 'arms which connect the master-wheel to the platform-frame may be treated as the wheel-frame, and its relative movements are shown in Fig. 1 in dot-ted lines. The board J is secured to the top of the post H, and at its point to the forward ends of the angle-bars, being socketed into the point G4.

In order that the strut-post H may gain a firm and rigid attachment to the finger-bar, and afford like rm securement for the divider-board J, it is formedwith the horizontal foot-pad H at the lower end, fitted to the finger-bar, and with the oblique pad h at the upper end, on which the board J may rest and be supported throughout its breadth.

I 'am aware that a spring has been used in a mowing machine to assist the raising of the cutter-bar; also, that elastic connections have been used in the lifting mechanism, with the purpose and effect of causing the cuttermechanism frame more easily to rise and fall in passing over inequalities in the ground; but in the latter construction the purpose of this invention is not attained at all, for the voperator has to lift the entire weight, notwithstanding the elasticity of the connections, and in the former case the construction is not applicable to a grain-harvesting machine of the character hereinv shown, because the lifting mechanism in the mowing-machine is mounted on the frame whose elevation is not changed in the adjustment, and the springs 'employed to assist the lifting are also connected to and act on the lifting mechanism by virtue of the resistance of the unadj usted frame, whereas in the machine herein shown it is essential that the lifting mechanism and the springs, which assist invoperating it and in lifting the adjusted frame, are mounted on the frame which is adjusted, and are themselves lifted with the frame which they lift.

I do not claim, broadly, the use of springs to assist the adjustment of the,cuttermechanism frame, but only design tov be understood as claiming the adaptation of such mechanism to a machine ofthe structure herein shown, wherein it would not be feasible to put such mechanism on the fixed frame.

What I claim is- 1. In combination with the wheel-frame and the platform-frame pivotally connected there to, adjusting mechanism mounted on the platform-frame and connected to the wheel-frame and additional elastic connection from said adjusting mechanism to the platform-frame, substantially as set forth.

2. .In combination with the two connected frames of a harvester, one of which is adjustable vertically, the mechanism whichY effects such adjustment mounted on the adjustable frame and rising and falling with it and connected to the other frame, and elastic connec tions additional to and independent of the adjusting mechanism operating connections and extending from said adjusting mechanism to the adjustable frame, substantially as set forth.

3. In combination with the two connected frames of a harvester, one of which is adj ustable vertically, adjusting mechanism mounted on the adjustable frame, and a screw- TOO IIO

shaft and suitable counterpart to operate the ing said adjusting mechanism to a fixed part Y of the adjustable frame, whereby said elastic connections relieve the operator in operating the adjusting mechanism, but cannot independently operate the same to change the adjustment of the frames, substantially as set forth. v

4. In combination with the wheel-frame cornprising the two lever-arms, the main or platform frame pivoted on one of said lever-arms, and the mechanism which adjustably connects the other arm to the platform-frame, the elastic links, one or more, which further connect said adjusting 'mechanism to the platformframe, substantially as set forth.

5. In combination with the wheel-frame comprising two lever-arms, the platform-frame, pivotally connected to one of them, the rockshaft C and its lever-arms, and the non-elastic IIR IBO

links from said lever-arms of the rock-shaft to the other lever-arm of the wheel-frame, and the elastic links which connect the non-elastic links to a iXed portion of the platform-frame, substantially as set forth.

6. In combination with the divider-frame having the post H at the rear of the vertical plane of the finger-bar, a lever, as the supplemental frame K, pivoted at the rear part of the divider-frame, and having the forward end guided by the post H and protruding forward of said post, the chain m, connected to said forwardly-protruding end and extending along the nger-bar around suitable guides at the grain and stubble ends thereof, and the mechanism at the stubble end of the machine for drawing and relaxing said chain to raise or lower the grain end, and thegrain-wheel having its bearings supported on said supplemental frame, substantially as set forth.

7. In combination with the divider-frame having the post H, vertically slotted, the supplemental frame K, pivoted at the rear end to the divider-frame and guided at the forward end in the slot of said post and protruding through said slot, and the chain m, connected to the protruding end and guided along the finger-bar to the stubble end, and the mechanism at the stubble end for drawing and relaXing said chain, and the grain-wheel having its bearings supported on said supplemental frame, substantially as set forth.

8. In combination with the divider-frame having the post H, vertically slotted, the supplemental frame K, pivoted at the rear end to the divider-frame and guided at the for- Ward end in the slot of said post and protruding through said slot, and provided with the lugs k7 and the anti-friction rolls thereon, and the chain in, connected to the protruding end and guided along the finger-bar to the stubble end, and the mechanism at the stubble end for drawing and relaxing said chain, and the grain-wheel having its bearings supported ou the said supplemental frame, substantially as set forth.

9. The trussed divider consisting of the parts G, G', and G2 and the post H, its rear end adapted to be secured to the rear platform-sill, and post adapted to be secured to the front sill, substantially as described.

10. The combination of the bars G, G', and G2 and the post H, adapted to be secured to the said bars and to form a footing for securing the said divider to the sill, and having the pad L for supporting the board J, substantially as described.

1l. In combination withthe upper andlower truss-bars of the divider secured together at front and rear ends, the post H, forming a Strut for the truss, and having the foot-pad for securing the finger-har, and the head-pad for securing the divider-board.
